ENVELOPE.

TO ALL WHQM IT MAY CONCERN:

I Be it known that I, HENRY Evn nn'nLL, of the city, county, and State of NewYork, have invented a certain new and useful improvement in Envelopes, of which the following is a full, clear, and exact description referencebeing had to the accompanyingdrawing, forming part of this specification, and in which- Figure 1 represents a rear view of an envelope constructed according to my improvement.

Figure 2, a transverse seetion of the same; and

Figure 3 a rear view of a similarly constructed envelope, but modified in shape.

Like letters indicate likeparts throughout the several figures. v

This improvement relates to what are known as hard or wedding envelopes, in which the flap of the envelope 'is usually left open ornnsealed, and myinvention consists in providing the one wing or portion oi the back of the envelope withan incision into. which the tongue of the-loose wing or flap is made to fit, and so-embossing such two connecting portions, and furnishing said flap with a bow or knot of ribbon, as that while the envelope is'lrept shut, but in a manner thatreadily admits of it being opened without tearing the flap by simply drawing thetongue out of the incision in the back, said tongue appears to project through a strap in the-buck, and as if tied by the bow, thereby giving a neat andornamentnl finish to theenvelope with protection againstilaring 'open,.and yet having all the advantage and convenience of an open envelope.

Referring to the accompanying drawing, A represents the loose or open flap of the envelope, and at its tongue, which, in closing the envelope, is projectedthrough an incision, '6, into, within, or under the back wing 13, that is embossed on the outside, as at c c, witli's'figure corresponding to the shape of the tongue and embossing d on the tongue and flap, and-which back is further embossed with a figure or lines, e'e, resembling a crossstrap, the whole giving to the tongue the appearance of its being projected through a cross-strap, while a bow 'or khot, C, that may be of satin ribbon, on the tongue or flap above the imitation strap, gives a tied or knotted aspect to the flap, which, though the insertion of its tongue within the incision 12 keeps the envelope from flaring open, is nevertheless free to be opened without tearing, unsealing, or untying, by simply drawing the tongue at out of the incision b. The-deception of the envel opes lock or tie by the bow C will restrain its being opened .by many not warranted to do so. Of course the shape of the wings and flap, with its tongue and lines or figures embossed on it, may be varied at pleasure. In figs. 1 and 2 the opening flap is shown as rnnningthe width of the envelope, and in fig. 3 as opening endwise.

What I- claim as my invention, and desire to secure by Letters Patent, is- The envelope, constructed substantially as described, with a flap and tongue, the latter fitting through an incision in a closed wing or portion of the back, and the tongue or flap and wing into which it fits being embossed and provided with a bow orknot to give a secured aspect to the envelope, while it is left free to open, yet protected against flaring open,- substantially as specified.
